I am a single mother of 2 children. In the event that something happens to me, I wish custody of my children to go to the maternal grandparents. The childrens father is scarce in thier lives at best (having seen them 6 times over the last 3 years). If this is docuumented in my living will, is it enforcable, or will the biological father automatically get custody in the event of my passing?I am married and have 3 children from a previous relationship. If I was to pass who would get custody of my children? The biological father who's not a part of my childrens' lives, or my husband who is acting as their father?
